The accompanying condensed consolidated financial statements have been prepared by CTS Corporation (“CTS”, “we”, “our”, “us” or the “Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements should be read in conjunction with the financial statements, notes thereto, and other information included in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2024.

The accompanying unaudited condensed consolidated financial statements reflect, in the opinion of management, all adjustments (consisting of normal recurring items) necessary for a fair statement, in all material respects, of the financial position and results of operations for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ materially from those estimates. The results of operations for the interim periods are not necessarily indicative of the results for the entire year.

There have been no material changes in the Company’s significant accounting policies as compared to the significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Immaterial Correction of Prior Period Error

As reported in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2025, the Company identified immaterial prior period errors in the consolidated financial statements related to the acquisition of SyQwest, LLC (“SyQwest”) as well as the foreign currency impact on certain long-term debt payments. The errors related to the SyQwest acquisition were due to errors with the calculation of revenue and cost of goods sold both prior to and subsequent to the acquisition date of July 29, 2024. The Company assessed the materiality of this change on prior period consolidated financial statements in accordance with SEC Staff Accounting Bulletin No. 99, “Materiality” (ASC Topic 250, Accounting Changes and Error Corrections). Based on this assessment, the Company concluded that these error corrections were material in the first quarter of 2025, but are not material to any previously presented consolidated financial statements. Accordingly, the Company corrected the previously reported immaterial errors for the year ended December 31, 2024 and the three and nine months ended September 30, 2024 in its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2025.

The financial reporting periods affected by this error include the Company’s previously reported audited consolidated financial statements for the fiscal year ended December 31, 2024 and the Company’s previously reported interim unaudited consolidated financial statements for the three and nine months ended September 30, 2024. In addition, the Company expects to present the corrected interim 2024 amounts in its 2025 consolidated interim financial statements upon the filing of each of its Quarterly Reports on Form 10-Q on a year-to-date basis as a correction to applicable 2024 periods. A summary of the immaterial corrections to the Company’s previously reported audited and unaudited consolidated financial statements follows.
